WINDOWS SERVER 2012 ERROR LICENSE SERVER

Recently faced with an unexpected problem, in January I installed and configured windows server 2012, everything was done by TK

ie used Windows Server 2012 in a workgroup (without domain), sets purchased client certificates to connect to the terminal server

installed and activated the license server.

Everything worked fine exactly 120 days after the error occurred

“The remote session because there is no available license servers a terminal server to provide a license. Contact your server administrator”.

Originated the actual question how and why.

First went in

The server Manager\remote desktop Services\Servers

Check that

1. Windows server 2012 activated

2. Services are started: remote desktop , remote desktop licensing

Later in

Server Manager\Local server

there they discovered the mistake

Grace period for remote desktop license has expired, and the service was not registered on the license server with installed licenses. For continuous operation the license server for the rd. The host server remote desktop session can run without a license server within 120 days from initial launch.

and

not set the licensing mode for the rd

However, the licensing mode is selected,and the licensing service is configured and the server is activated.

It turned out that in the latest versions of microsoft windows server 2008 2008 r2 2012 recommend the use domain, while both the licensing regime,

and in the absence of a domain is only possible licensing mode on the device, and after 120 days the license mode user stops working and the server becomes impossible to connect via RDP.

Important ! If we choose the licensing mode to user then the error will remain and the server to continue to repeat that there are no license servers available , because the working group can only be licensing mode on the device.

Later in the same run gpupdate powershell, Next you need to perepoloshit license for this
